Intel's family of Intel Ethernet X520 Server Adapters with SFP+ connectivity is the most flexible and scalable Ethernet adapters for today's demanding data center environments. Data center networks are being pushed to their limits. The escalating deployments of servers with multi-core processors and demanding applications such as High Performance Computing (HPC), database clusters, and video-on-demand are driving the need for 10 Gigabit connections.
Best choice for virtualization
The explosive growth in virtualization is leading to an increasing demand for network performance. With more Virtual Machines (VMs) running on each multi-core server, networking traffic is dramatically increased with each VM competing for available I/O bandwidth. Intel's family of Intel Ethernet X520 Server Adapters addresses networking bottlenecks in virtualized environments. These adapters enable network-intensive applications to achieve the performance expected in a virtualized environment. The Intel Ethernet X520 family of Server Adapters provides the best networking performance available in the industry, whether the physical port is configured in an emulation mode using the virtual switch in the Virtual Machine Monitor (VMM), or is directly assigned to a virtual machine.
Unified networking and storage
The family of Intel Ethernet X520 Server Adapters lowers your data center total cost of ownership (TCO) by providing the ability to route LAN and SAN traffic over a single fabric.
Support for Fiber Channel over Ethernet (FCoE)
FCoE encapsulates Fiber Channel frames over standard Ethernet networks, enabling Fiber Channel to take advantage of 10 GbE networks while preserving its native protocol. The X520 server adapters offer FCoE hardware acceleration to provide performance comparable to FC HBAs. The server adapters support Data Center Bridging, also known as Converged Enhanced Ethernet (CEE), which allows customers to configure traffic classes and priorities to deliver a lossless Ethernet fabric. An Intel Ethernet X520 server adapter reduces TCO by eliminating redundant fabrics and saves the cost of expensive FC HBAs and FC switch ports.
Support for iSCSI
The server adapters provide complete support for proven native OS and VMM iSCSI initiators as well as iSCSI boot. Historically, CRC32C computation has degraded system performance, but now with the CRC instruction set included in the Intel Xeon processors, CRC validation is possible with minimal impact to network throughput while delivering superior data integrity.
The family of X520 server adapters includes a number of advanced features that allow it to provide industry-leading performance and reliability.
The adapters support IPsec offload for Microsoft's Network Access Protection (NAP), Active Directory, and future security capabilities in Windows 7. An X520 server adapter allows customers to run a secure network environment without sacrificing performance.
PCIe v2.0 support enables customers to take full advantage of 10 GbE by providing a maximum of 20 Gbps bi-directional throughput per port on a single dual port card.
Designed for multi-core processors
Support for technologies such as multiple queues, receive-side scaling, multiple MSI-X vectors, and low latency interrupts allow the X520 Server Adapters to provide high-performance, 10 Gigabit connectivity in multi-core server blades. These technologies distribute network processing across multiple CPU cores, improving overall performance.
